Great Product!By paulon 7/19/2012

I have had this unit for over two years. It works great and I have had no problems with it. I love not adding top off water every day! I use a 20 gallon Brute trash can for my RO/DI top off water and that lasts me two weeks for my 240 gallon tank. If you are going to use it with a kalk Stirrer I would recommend using a PH controller because if you have a small leak or start doing a water change before you unplug it, you could get concentrated kalk into your tank pretty quickly.

Do not hesitate to purchase this the price point is worth it the peace of mind and lack of necessity to spend the daily fill up is worth every cent and on top of that the wife will actually like the functionality of this piece of equipment.

Everyone should own a Tunze auto top off. Really easy to setup and works great. This is a perfect device.

Great upgrade, don't have to worry about water top offs everyday.By Moiseson 6/17/2012

This is one of the best upgrades you can add to your system. Yes the price is a little high but your paying for a high quality product that is fail safe and will give you peace of mind. Not to mention no more daily top off chores. The system is easy to setup and the magnets make placing the sensors hassle free and give you the ability to place them where ever you want. If your going to buy a ATO system this is the only one to consider.

Can't beat the quality of the Tunze Osmolator and BRS price and service. The dual sensors and sturdy magnet mounts provide peace of mind. I feel safe with this system.

Have had it for a while now and rely on it completely. Have never had an issue with failing in the on position like float switches tend to do. Would highly recommend.

Magnet holders are also a plus as placement is a snap.

Its my first time purchasing an ATO system, after seeing the price I did not think that I was going to buy this system, but after knowing that its fail safe I decided to get one. It works awesome and I would recommend.

Simple, easy to use. Only downside i see is when doing water changes you must unpower it.
